128K X 8 HIGH SPEED CMOS STATIC RAM
GENERAL DESCRIPTION
The T14L1024A is a one-megabit density, fast static random access memory organized as 131,072
words by 8 bits. It is designed for use in high performance memory applications such as main
memory storage and high speed communication buffers. Fabricated using high performance CMOS technology, access times down to 10ns are achieved. Memory expansion by banking is easily accomplished using the chip enable pins CE1 and CE2. This device is packaged in a standard 32-pin 300 mil DIP/SOJ and 32-pin SOP/TSOP-I.

Notes: 1. During this period, I/O pins are in the output state, so input signals of opposite phase to the outputs should not be applied. 2. The data output from D OUT are the same as the data written to D IN during the write cycle. 3. D OUT provides the read data for the next address. 4. Transition is measured ± 500 mV from steady state with C L = 5pF. guaranteed but not 100% tested. This parameter is
5. If OE is low during a WE controlled write cycle, the write pulse width must be the larger of tWP or (tWHZ + tDW) to allow the I/O drivers to turn off and data to be placed on the bus for the required tDW. If OE is high during a WE controlled write cycle, this requirement does not apply and the write pulse can be as short as the specified tWP.
